MACHINE FOR SAWING FELLIES SPECIFICATION forming part of Letters PatentNo. 617,005, dated January 3, 1899.

Application filed June 29, 189 8. Serial No. 684,730. (No model.)

To (tZZ whom it may concern:

Be it known that I, ALEXANDER C. Wool), a citizen of the United States,residing at Advance, in the county of Davie and State of North Carolina,have invented a new and useful Machine for Sawing Fellies, of which thefollowing is a specification.

My invention relates to sawing-machines, and particularly to anapparatus for sawing follies; and the object in View is to provide asimple, compact, and efficient construction and arrangement of partswhereby the uniform sawing of fellies in sections may be accomplishedwith facility and accuracy.

Further objects and advantages of this invention will appear in thefollowing descrip tion, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a felly-sawingmachine constructed in accordance with my invention. Fig. 2 is centralvertical section of the same, taken in the plane of the saw-arbor. Fig.3 is a plan View of the holder or carriage.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The supporting-frame 1 maybe of any suitable construction, that which isillustrated in the drawings consisting of corner-uprights 2, connectedby transverse and longitudinal bars 3 and l and an intermediatecross-bar 5. Mounted in suitable bearings 6 upon one of the end bars andsaid intermediate cross bar is a saw-arbor 7, carrying a belt-wheel 8 orequivalent means for communicating r0- tary motion to the arbor. Fixedto the sawarbor are the twin concavo convex sawblades 9. Supported bysaid framework is an inclined table 10, suitably braced at its underside and disposed at an inclination to the horizontal plane of thesaw-arbor to suit the desired angle between the edgeand side surfaces ofthe felly-sections to be cut and also to suit the dish of the wheels ofwhich said folly-sections are to form parts. Mounted for oscillatorymovement upon this table is a work holder or carriage 11, of which thepivot-bolt 12 is at a point in alinement with the saw-arbor andconcentric with the concavo-convex saw-blades. The floor of the holderor carriage, which is arranged in a frame consisting of parallel sidebars 13 and convergent end bars 14 (at the apex of which is arrangedsaid pivot-bolt)is slotted,as shown at 15, concentric with thepivot-bolt 12, and one of the side walls 13 of the holder is kerfed, asat 16, in registration with the slots 15, to allow the saw-blades, whichoperate in said slots 15, to pass into and out of the same.

The parallel side walls 13 are spaced at an interval correspondingapproximately with the length of the blocks from which the fellysectionsare to be sawed, and in one of the said walls, preferably opposite tothat in which said kerfs 16 are formed, is mounted a clamp-screw 17,carryinga swiveled clampplate 18, to bear against the end of a block,such as 19, arranged in the holder and provided at its outer end with acrank or similar handle 20. When a block is to be sawed, the holder orcarriage is swung upon its pivot to carry it beyond the saw-blades,whereby the latter are withdrawn from the slots 15, the block isarranged between the side walls of the holder, and the clamp-screw istightened to secure the block in place. The holder is then swung uponits pivot in the opposite direction to cause the saw-blades to enter thekerf 16, and therefore the slots 15, and simul taneously sever afolly-section from the block.

From the above description it will be seen that the construction issimple and that the entire operation thereof is under the control of theattendant, the side walls 13 being preferably extended to form grips 13,by which the attendant may swing the holder in the desired direction toeither remove the saws from the slots or feed the frame during thesawing operation.

A further advantage of the construction described resides in the factthat the sawarbor is arranged in a horizontal plane, and hence thepulley can be traversed by a belt extending from an ordinarydriving-shaft, such as those arranged in shops of the class in whichmachines of this kind are ordinarily employed. It will be seen,furthermore, that by reason of the specific construction of the holderor the carriage, with its spaced walls 13, between which the block ofmaterial is arranged, no endwise displacement of the felly-section canoccur during the sawing operation, and hence the accuracy of the work isinsured.

Various changesin the form,proportion,and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. In a fellysawingmachine, the combination with a supporting-frame, of ahorizontally-disposed saw-arbor carrying concavoconvex saw-blades, atable arranged at an inclination to the saw-arbor, a holder or carriagepivotally mounted for oscillatory movem ent upon said table and providedin its floor with parallel slots for the reception of the saw-blades,said holder also having upstanding side walls, and the pivot of theholder being concentric with the saw-blade, and a clamping devicearranged at one edge of the holder between the planes of the contiguousends of the slots in the floor thereof for securing a block of materialin the holder by forcing the opposite end thereof against the remoteside wall, substantially as specified.

2. In a telly-sawing machine, the combination with a supporting-frameand a saw-arbor mounted thereon, of a table arranged at an inclinationto the plane of the saw-arboiytwin concavo-convex saws carried by thesawarbor, and extending upwardly above the plane of the table, a workholder or carriage pivotally mounted upon the table and provided in itsfloor with parallel slots for the reception of said saws, said holder orcarriage also havingspaced side walls, in one of which are formed kerfsin alinement, respectively, with said saw-slots, to allow the removal ofthe saws from the interior of the holder, and clamping devices forsecuring a block of material in the holder, one of said side walls beingextended rearwardly to form a carriageoperating grip or handle,substantially as specified.

3. In a telly-sawing machine, the combina tion with a supporting-frameand a saw-arbor mounted thereon and carrying twin concavoconvexsaw-blades, of a table arranged at an inclination to the plane of thesaw-arbor, a work holder or carriage pivotally mounted upon the tableconcentric with said sawblade and provided in its floor with parallelsaw-slots for the reception of the saws, said holder also havingparallel side walls in one of which are formed kerfs respectively inregistration with the saw-slots to allow the removal of the saws fromthe interior of the holder preparatory to the arrangement of a block ofmaterial in the latter, and a clamping device, consisting of aclamp-screw, threaded in the other wall of the holder between the planesof the adjacent ends of said saw-slots and carrying a swiveledclampplate for engagement with the extremity of a block introducedbetween the side walls of the holder and supported by the floor thereof,said clamp-screw being provided with an exterior operating-handle andbeing adapted to force the block against the kerfed wall of the holder,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

ALEXANDER C. XVOOD.
